Help with Weak Aura

Hello! I’m trying to make a WA to “cover” the nameplates with some animation, glow, a square or something (dunno how to explain it well) when my debuff is active on an enemy.

To track my lashing flames with enhancement shaman. Is that possible? And how can i do it?

Thanks

Should be able to just do “New Aura>Stop Motion” and match it to the spellID, yeah?
